Amazon ElastiCache for Valkey introduced support for data tiering on Graviton4-powered R8gd nodes in Europe (Spain) and Graviton3-based R7gd nodes in both Europe (Spain) and Asia Pacific (Hyderabad) Regions. Data tiering leverages SSD storage alongside memory, moving less-used data to SSD when memory is full, to economically scale Valkey clusters to hundreds of terabytes.
Graviton4 nodes offer significant throughput and latency improvements compared to earlier generations, and Graviton3 nodes improve throughput and network bandwidth relative to Graviton2. Data tiering suits workloads frequently accessing about 20% of their dataset, balancing cost and latency tolerances. This expansion enables broader global availability of high-performance, scalable caching with tiered storage.
